"At the moment, we know that Liverpool is interested. But that's all it is at this point, an interest," Fassi told ESPN.Fassi maintains that any potential move made will have to be on a permanent basis, though, before stating his belief that Herrera would take the Premier League by storm.He continued: "If [Herrera leaves], it will be thanks to a sale. We will not loan him out or send him for a trial.""[Herrera] can surely be one of the Premier League's best players in two or three seasons. He's that good."
